I am thinking I will have to do a complete wipe of my Nexus 7 because it has slowed down terribly in the last couple of weeks and I have no idea why no new apps installed recently. I am tolerant of the normal jitters here and there but it has become pronounced. Maybe it was a recent update to an app, my only real change has been using Google Play All Access Music (or whatever they named it, sheesh what a mouthful). Was planning to backup app data, then re-download the most used apps one by one until I find the culprit. Do any of you use/like/dislike Helium or have an alternative that would allow me to backup - I am not rooted, and only download from Google Play Store. Or is there an app that shows which apps are hogging the device? I don't see any suspicious apps in Settings>Applications>Running. Any thoughts would be appreciated!
